Description

 Performance and Feature:
1. 2.5T underground mining battery locomotive owns small volume and compact design. 2.5T underground mining battery locomotive are used for hauling materials and equipment and were specially designed and built for work in narrow tunnels with tight curves and steep gradients.
2. 2.5T underground mining battery locomotive adopts DTC frequency conversion (motor direct torque control with null rotate and full torque) as speed control. The frequency converter invert direct current supplied from battery to three-phase alternating current by IGBT(Insulated Gate Bipolar Transistor) and the timing circuit is regulated only by the exterior potentionmeter.
3. 2.5T underground mining battery locomotive is built in protecting circuit and abnormal warning against over-current, over-heat, over voltage, over low voltage, by which ensure secuity. When brake and decelaeration, the battery can be charged by the electric energy from motor at same time, by which extend working hours and reduce charge times.
4. 2.5T underground mining battery locomotive prolong the battery working life greatly. As the locomotive adopts rotational speed control in whole process, it gets bigger torque when starting, regulates safer when downslope of heavy haul, which preventing from accident effectively.
Use:
The high technology, reliable performance, simple maintaining, economical and high-efficiency makes the 2.5T underground mining battery locomotive fit for all kinds of tunnel projects and mines. For small coal mines, non-coal mines, tunnel engineering , construction projects and so on, the 2.5T underground mining battery locomotive is second to none.
